Advanced CNC Techniques with Basic Features

Course Cost: 6 Month Subscription

Basic Course (no certificate) = $99.00
Course with Online Certificate* = $124.00

Advanced CNC Techniques with Basic Features is the 6th course in Mike Lynch's CNC Machining Center programming series. The primary goal for this course is to expose the student to as many potentially helpful techniques as possible. Students having limited experience with CNC (less than six months) will be shown countless new techniques that can help. Even experienced CNC people may be surprised at how many techniques they have not been shown. As a secondary goal, we hope to get students thinking outside the box. We call it "aggressive awareness". By seeing how others have solved problems and made improvements, students should begin to see how they can improve their own CNC environments.

Course Description

Many people completing our basic programming courses stated (in the course evaluation) that they would like to see us provide an on-line Advanced CNC Techniques course. Well, here it is! It is the next logical progression from our basic courses. We define an advanced technique as any technique that is not commonly presented in a basic CNC class. Many of the techniques we show are quite easy to understand - they're just not among the first things you learn. Additionally, we say an advanced technique is any technique that you don't currently know about that can help you. Indeed, even many experience CNC people will probably discover techniques that they have not been exposed to.

Benefits that can be achieved by applying the techniques we show include reducing setup time, reducing cycle time, improving workpiece quality, shortening programs, making machines easier to run, improving your company's CNC environment, and in general, improving your knowledge of CNC. Indeed, given the high costs associated with running CNC machine tools (and the low price of this course), it's likely you'll pay for the cost of this course with the first technique you apply!

We present many techniques for the two most popular forms of CNC metal cutting equipment. For each topic, we'll begin by showing techniques that these two machine types share in common. Next, and when applicable, we'll show machining center-related techniques. Finally, we'll show turning center-related techniques. While this class will be of most value to people that work with both machining and turning centers, even people that work with but one or the other should find plenty of techniques that will help them

Course Lessons

Lesson 1: Understanding parameters

All CNC people should be aware of how parameters affect how CNC machine tools behave. Included: Introduction, eight bit binary type, whole number type, how parameters affect machines, backing up.

Lesson 2: Documenting in the program

All CNC programmers should include adequate documentation within the programs they write. This lesson discusses the most important times when documentation should be included in the program.

Lesson 3: Block delete techniques

Block delete (also called optional block skip) can be used when you want to give the operator a choice between one of two possibilities. Included: using block delete mid-command, trial machining, allowing for exess stock, and muliple block deletes.

Lesson 4: Techniques with sequence numbers

While sequence numbers (N words) are extremely elemetary CNC words taught in every basic CNC course, there are some advanced implications of their use. Included: identifying restart commands, statement labels.

Lesson 5: G code commonalities

G codes share certain things in common. In this short lesson, we explore commonalities. Included: maximum number of G codes per command, monitoring current G codes, setting initialized states.

Lesson 6: Techniques with motion types

The basic motion types (G00, G01, G02&G03) are usually well covered in basic courses. There are, however, some techniques we'd like to relate. Included: G00-G01 for positioning, which is faster G00 or G01?, techniques with circular motion.

Lesson 7: Special motion types

Control manufacturers provide special interpolation types for special applications. These motion types are seldom covered in basic courses. Included: helical interpolation, spiral interpolation, cylindrical interpolation, polar coordinate interpolation.

Lesson 8: G04 - dwell techniques

The dwell command is used to cause axis motion to pause for a specified period. It may not be mentioned in some basic CNC courses. Included: dwell period options, relieving tool pressure, programming around machine problems, exact stop check.

Lesson 9: G10 data setting command

G10 can be used to program data entries (offsets, parameters). It is rarely discussed in detail during basic CNC courses. Included: how G10 works, tool length and cutter radius offsets, tool nose radius offsets, work shift values, parameters.

Lesson 10: Plane selection G17, G18, & G19

Plane selection commands are used (especially on machining centers) to tell the control whether the program will be machining in the XY, XZ, or YZ plane. Included: right angle heads, circular motion, canned cycles, cutter comp.

Lesson 11: Inch / metric selection

Most current model CNC machine tools allow you to work in either the inch (English) or metric system. Measurement system modes aren't discussed in most basic CNC courses. Included: Switching, advantage of metric mode, what happens when switching.

Lesson 12: Motion manipulation techniques

There are several special CNC words that can be used to manipulate the way the machine will perform motions. Included thread cutting, polar coordinates, scaling, mirror image, coordinate rotation.

Lesson 13: Radius compensation G40, G41, & G42

While this feature is covered in most basic CNC courses, most barely scratch the surface of what is possible, and most do not warn you about potential problems. Included: two ways to use, handling problems, limitations, programming offset entries.

Lesson 14: Tool length compensation

While tool length compensation is well covered in most basic CNC classes, there is one special technique that is not usually discussed. Included: using secondary offsets, if mistakes are made.

Lesson 15: Spindle limiter G50

While some basic CNC course mention G50, there are several things that are not discussed. Included: How G50 works, chuck changes, changing parameters to set max speed, with bar feeders.

Lesson 16: Coordinate system techniqes

Program zero assignment is covered quite well in basic CNC classes. Here we show some extentions of what is covered. Included: temporary shift of program zero, causing rapid motion relative to zero return position, advanced fixture offset techniques.

Lesson 17: Canned cycles G73 to G89

Canned cycles are covered in basic CNC courses, but there are several advanced implications. Included: parameters to improve efficiency, L0, canned cycles in the incremental mode.

Lesson 18: Constant surface speed G96

While constant surface speed is well covered in most basic courses, it can be a cycle time waster if it is not properly programmed. Included: minimizing the effect of constant surface speed on cycle time.

Lesson 19: M codes

Most M codes are covered in basic courses. However, there are some important points that are not commonly made. Included: M codes within motion commands, M codes you don't aggree with, high low spindle range.

Lesson 20: T word techniques for turning centers

The T word is covered in most basic courses, but several advanced implications are not. Included: Right or left hand tools, canceling wear offsets with T0, secondary offsets.

Optional Certificates Awarded

Certificate of Outstanding Achievement

In addition to the standard Certificate of Course Completion, Merit Awards may be issued by the instructor at his/her own discretion and are based on student achievement. Merit awards also incur an additional $30.00 processing fee that covers the customization, printing, and delivery of the award, as well as access to the UniversalClass™ Portfolio Service that documents your achievements online.
